Abstract
Transmission and distribution networks are facing the challenges of large shares of renewable generation (RES), electric vehicles (EVs) and heat pumps (HPs), all affecting network operation to a large extent. In order to avoid massive and costly network reinforcement, flexibility offered by active customers can be used. Flexibility services provide clear benefits for distribution system operators (DSOs) in terms of voltage control and congestion management, maximizing RES, EVs and HPs integration. For the activation of flexibilities located in distribution networks a systemic approach is needed. Firstly, the distribution system operator has to be capable of estimating and forecasting the state of the network (voltages and power flows) and calculate the network operational constraints in terms of maximum power consumption or generation in a particular network node. Secondly, an aggregator has to aggregate the customers flexibility that can be provided to power system stakeholders. In addition, the aggregator has to be aware of the distribution network operational constraints. And thirdly, the link between service requirements and the available flexibility of active customers is represented by the market operator. All three aspects of the local flexibility are addressed in the proposed DN-FLEX project. The overall objective of the proposed project is the creation of local flexibility market platforms, which will enable to exploit the network customers flexibility for distribution network operation and for provision of services to other power system stakeholders. The services will be provided according to distribution network operational constraints. This approach will result in an increase of the network hosting capacity and utilisation, reducing substantially the costs for network reinforcement. To achieve this objective, the state forecast, and the distribution-network node capacity (DNNC) modules will be developed within the project, forming the Distribution network constraints platform. From the DNNC, two important parameters can be derived: If the network operational constraints are violated, or they will be violated in the forecasted future, the output of the DNNC gives the required services that will bring network operation within limits.In case network operational constraints are not violated, the output of the DNNC gives the maximum range of flexibility that can be provided as a service to other market participants. On the aggregator’s side, the Flexibility aggregation platform will be upgraded so that it will take distribution network constraints into account. On the market side, the Market operator platform will be developed, including a service scheduling module for the provision of services based on the service demand and flexibility supply offer. The developed platforms will be tested in a pilot project within an actual LV network. Within the network, additional measurement devices will be installed in order to provide sufficient data for the state estimation and forecast process. The developed algorithms will be operating in real-time, constantly calculating the network DNNC and providing these data to the aggregator platform. This will result in the assessment of customers flexibility according to the available network capacity. Based on the distribution network needs and the available flexibility the services will be activated by the market operator platform. The project results will be evaluated, and a scalability and replicability study will be carried out, with the Advanced network planning tool, which will be also developed within the project. The co-financers of the project are the energy supplier GEN-I, the DSOs Elektro Gorenjska, Elektro Ljubljana and Elektro Celje, and the TSO ELES. Their cooperation shows the interest of key stakeholders in the implementation of the local flexibility market and provides appropriate support for the implementation of the project.
